Results

MRSA-resistance rates and the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) have remained at a stable level over the last few years. In contrast, vancomycin-resistant enterococci (VRE) and multidrug-resistant gramnegative (MRGN) bacteria have increased considerably. VRE prevalence has more than tripled in the past 5 years, and Escherichia coli resistant to third-generation cephalosporins, acylureidopenicillins, and fluoroquinolones increased by 43% in 2015 compared with the previous year.

Conclusions

New policies to control MDRO should focus on VRE and the heterogeneous group of MRGN bacteria. In the case of the latter, the different bacterial species’ characteristics should be taken into consideration.
